keep in mind if your switching from a storm to a tour it is compatible but there are a few upgrades over and above the tour support. However there is a version out now for the tour it's self.
I could be wrong on the dates here but if you bought QL after april 1 or 30th (IDK for sure) it's considered an upgrade so it's only $1.99 and then you have to email mobihand and they will have to swap your device type and PIN.
I'm not eligable for that deal so I'm just gonna buy it for my tour!
